Filter Cleaning or Backwashing

The filter on your pool could be one of possibly three different types:

1. Diatomaceous Earth DE

2. Sand

3. Cartridge

Each has a different method for cleaning but all must be cleaned regularly either when the pressure gauge indicates or on a time basis (weekly, monthly etc) dependent upon the enviroment & the amount od dirt the filter collects.
